.Net schedulers?
-
I'm looking into using Quartz.net[^] but I haven't seen a good UI so that the user can schedule their own jobs. Just curious what other people have used. Have you exposed scheduling to end users? If so how detailed was it, meaning could the user choose which days of the week, or perhaps every 3rd Tuesday, etc.

A long time ago I this this in Visual FoxPro. Essentially the user got to pick a job, which mapped to a DLL that was run via a scheduler. Mostly for running processes after hours, such as data aggregation. Now, I'm actually about now halfway through creating a scheduler app in C# 4.5/WPF. It looks like Quartz has many of the same features: 1. Allows the developer to create Groups which contains any number of Tasks. These are essentially assemblies that implement an interface with an "void Execute(object params, object data)" method. The developer codes the assembly and uses the "Publish" feature to put it on the server. Processes and task have an "Order" so you can control the sequence they run. 2. Has the same scheduling options as Windows Scheduler (Minutes, Hours, Days, Months, and Once Only) 2. WPF UI. 3. SQL Server 2008 accessed via WCF hosted in a windows service for single instance or in IIS for multiple server based scheduler instances for load balancing. 4. Allows passing of data returned from one process to another. 5. Full logging. 6. Email Notifications. I'd like to hear more about what you're looking for as far as requirements. I'll publish it here when I'm done.
If it's not broken, fix it until it is

Personally, I've always used plain .NET Console applications that are being started via the Windows Task Planner (or how it is called now) on e.g. a Web server. Always satisfied my needs.

Wouldn't you need someone to be logged on for that to happen? Wouldn't a windows service work better?

Yuck. A scheduler can easily get out of hand quickly. For example, you can support very simple schedules: weekdays, weekends; or very complex ones allowing the user to pick every other Wednesday during May, then every Thursday during June, etc. It can get complex quite quickly depending on how flexible you need it. Right now, I'm not sure how flexible the scheduling needs to be. Likely it will be on the simpler end of the spectrum. I just need something that allows us to schedule sql stored procedures, possibly command line exes, and who knows what else but is flexible enough we don't have to recompile code every time we need something new scheduled.

I configure the task to run when the system starts. I also configure a user to run under. Windows services are way harder to debug. I never had the need to use it when a console app also did the job.

Im using quartz.net and topshelf as a service base, with the 'jobs' defined in a json config & using cron triggers - so if I were going to allow a user to edit the jobs, I'd be looking at something that could edit the json definitions

I'm not sure if it's related or not, but a current project is an import designed to run as a scheduled task on a server. The user can take care of the schedule and the service account. I originally had plans to do it as a console app, but after building the POC as a WinForm app, decided that I liked having a UI for manual mode/setup, and just added in whatever command line args I needed, including a /silent mode to suppress messages.

I once had a similar requirement from some PM, I got sick of him defining ever more detailed needs that he had thought up and simply shoved up a calendar and told him to pick the days and times he wanted it to run. At some point it goes beyond "scheduling" and becomes random events!

I wish I could help. I wrote something that languished unupdated a long time before quartz.net was written. (here)[^] Unfortunately, I never got around to writing a UI component for the project, but that was always meant to be the next step. There really should be a solid solution for that somewhere.

I used RadScheduleView from Telerik for the UI and for the scheduling engine. The requirement was to look and act like Outlook Calendar and it does. The UI maintains a set of tables with in SQL Server with all the schedule info. I customized/extended the ScheduleView to hold info about the task I wanted scheduled. A task is just an exe that will run. I created a Windows Service with Topshelf which makes it really simple to create and debug (your service is just a console app you write). The DBA did not want the service to poll the database for schedule changes too often, so the UI raises an "event" thru MSMQ to notify when the schedule is changed. The service listens to the queue, hitting the database one time in the morning for today's schedule and any time a schedule change is queued. It is not as complex as it may sound really. Total dev time was about a week.

Using console app + built in Windows Scheduler. Does the job.

I used to think that I wanted a job scheduler to do things, but I thought all the .NET ones were over-complicated. So, I spent a couple hours or so and wrote one in to my app. Just have a timer that checks your configured jobs every interval (maybe a minute or less) if it's time to run one, then run it. There's a few other complexities to deal with, but it's not as hard as you think. Think about the configuration for Unix chron as the simplest way do it with lots of timing options.
